SPECIFICATION forming part of Letters Patent hie-598,971, dated February 15, 1898. Application filed August 3, 1896. Serial No. 601,412. (No model.)

I To aZZ whom it may concern: 1

Be it known that I, CHARLES C. A. BAUER- CAMPER, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain useful Improvements in Locks; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification. i

This invention relates to that class of keyless locks in which a series of operating-stems projectfrom the housing and which are so arranged that the lock may be operated by means of these projecting stems.

In the drawings I have shown a padlock em bodying my invention.

A great many locks are I being used in securing bicycles. It is found, however, that these locks occasionally are hard. to unlock, especially in the dark. At night the most careful riders in leaving their wheels for a short time secure the same by locking them, usually with an ordinary padlock. Thisis an easy method usually, as these locks are generally made to readily snap. in looking. To unlock these locks, however, in the dark is often a very trying procedure, in that the small key-slots are difficult to find.

To provide a lock which can be operated in the dark or by a blind operator fully as well as a lock which can be unlocked in the daytime and by a seeing operator is the aim of this invention.

In the accompanying drawings, Figure 1 shows a view, with parts removed, of an ordinary padlock constructed according to my invention. Fig. 2 shows an elevation of the tumblers. Fig. 3 shows a top view of the bolt-link as used in my invention. Figs. 4 to 9, inclusive, show views of the various tumblers as disconnected. Fig. 10 shows a detail of one of the operating-buttons and connected stem, while Fig. 11 shows a detached view of the dog as used in may look.

My invention comprises, essentially, a lockhousing A, of any suitable size or material, which is provided with the upwardly-extending flange B, which flange, in conjunction with two similar plates A, forms my lockhousing. The flange B is secured to the plates A, which are both similar in size, shape,

and construction with the exception of one end 1) thereof, which end of the flange is loose and actuates as a spring, this flange B being of spring material. Secured to the plates A by means of a pin 1 is'the hasp 2,

which has an end 8 in the form of a lock"- seating, as is shown. The hasp is further provided with an extension 4, which operates against the flange end I) as a lever to press the same in when the hasp is closed, so that this hasp is normally under spring-tension in 6 5 working against the end I) of the flange B.

Positioned at a suitable pointwithin the casing is a shaft 5, upon which shaft are mountedseven tumblers, six of which, for

the sake of convenience, are mutilated, as is shown in Figs. 4 to 9, inclusive. The upper integral tumbler is numbered 6, the succeeding one 7, the following one 8, succeeded by the tumblers 9, 10, 11, and 12. Each of these tumblers is provided with a central opening adapted to accommodate the shaft 5, while each is further provided with a tumbler-incision a. The tumblers numbered 10 and 12, however, are provided with projections, the

tumbler 10 being provided with a projecting 8o downwardly-extending hook d, while the mutilated tumbler 12 is provided with a stub projection 6. Each tumbler, in addition, is provided with an opening 0, through which a pin g (shown in Fig. 1) is made to pass in securing these tumblers each to a bar 0, which bar is provided with an operating-button E, as is shown in the drawings. Each of these operating-buttons is made to pass through an opening within the flange B, these buttons 0 being held and guided within their openings. Upon the inside each operating-button is provided with a spring 15, working against the lower end of the button proper, so that each button is normally held outwardly under spring-tension, as will be understood in referring to Fig. 1.

Pivotally secured within the lock-housing is a lever H, secured by means of, the pivot 16, and to which is secured a stem 0', provided I00 with the button D, so that this lever H is normally held under spring tension in one direction. To prevent these buttons from passing too far outward, each is provided with a projecting pin 17, so that these operatingbuttons, with their bars and connected tumblers, are all held in a spring-locked condition, the pin 17 preventing the buttons from passing outward, while the spring 15 holds the buttons under spring tension inwardly.

Projecting from the lever H is a housing K, from which extends the dog K, which dog below is provided with a bolt-opening 20, as is shown in Fig. 11. Working within the housing K is a bar E, which is provided at the rear with the flaring head projecting beyond the housing and upon the inside'with a pin 21, and between this pin 21 in the bottom of the housing K is an ordinary expansion coil-spring 22 to normally force thisbar E outward to, form .a springrcatch, the. bar.

preferably passing through the lever for the sake of strength.

\Vorking adjacent to. the mutilated tum;

blersis a sliding link M, (shown as. detached.

in Fig, 3,) which is providedwith a central slot.25, which near the rear is provided with. the seating 26, in front with the projecting nosing. 27, and at the rear with a projection.

provided with aseating 28 and thebreast29, as is shown in Fig. 3. This. link is; held, in position by means of a pin N, andiupon. the

side provided with the seating 26is. further tion the. hook end at of the. mutilated tumbler.

10 rides within the slot 25. and-resting immediately within the seating 26, as. shown.

To open the lock, it .wouldbe. necessaryto. movethe dog, with its connected springcatch: ing-bar E, out of the seating 3. This, however, could not be doneunless, the slots or incisions a would all come within line, sotthat.

line, m 00 represents the position of thedog K,

it would be impossible tounlock the hasp,v unless the mutilated tumbler 8 werecarried toward the a side, so as. to bring its slot with; in line of the tumblers. 6, 7, 9, 11, and 12,

while the tumbler 10, however, wouldh ave.

to be carried toward the yside in orderto. bring about the alinement. This, asshown,

wouldrequire the depression of the button.

marked 8, as well as a depression of the. but.- ton marked 10. Should any other button,

however, be touched, it would of course carry, its connected tumbler. out of properalinement and preventth-e falling of the dog.

The arrangement of the tumblers. without the operation of thelink M would comprise an ordinary simple lock,which could be easily.

Inthis cornbi nation, referring now to Fig.2, where the.

ing andact as a bolt to. lockthe dog K, and

then, even though all the slots be in proper alinement, it would be impossible to depress the releasing-button 13,as the nosing 27 would securely lock the same. From this it will be seen that the tumbler 10 has two positions, so

that its slot a would come in true alinement In one instance, however, should the tumbler 10 have been actuated before the link M had been carried outward, the

with theudog K.

tumbler 10 would have carried the link forward'inalinin g its slot; bu t the forward movementwould.havepcarried the. nosing 27 into Fthe dog K2, so that while. all the slots were in .truealinementfon the admission of the dog this dog-slot would. havebeenheld inoperative. and solock in its closed condition by vir- 117110. of the. linkenosing being within :the dog. The buttonof the tumbler 10 has been so placed that it is the most easily touched, so

that should through any accident this tumbler be actuated before its proper interval in the permutation-of the lock thedog would be held. in a locked position, as has been described.

Should the mutilated. tumbler 12 be actuated alone, it would, bymeans ofithe projections 6, force the link M outward, so thatthe seating 28wouldengage the pin 31, in which position thelink would beheld. Theoutward movement ofthe link .then would .permitthe passageof the hook d, so. that the incisionor slotwithin themutilated .tumblerlO could be broughtinto. proper alinement.

If (a look. were constructed and arranged preciselyas isshown in Figs. 1 and2, the combination to unlockthe same would be as follows; Depress. 8, 12, then 10, then release 12, and finallydepress. 13, when thelockcould 'be opened.

In referring to Fig. 2, 8 would have been depressed to bring its slot into alinement. Next 12 would .have been depressed; but this depression was notmade to bring its slot into alinement, as this slot already was in proper position; but the depression was madeso that the, projection 6. would engage the breast29 ofthelinkto carry this. link outward. The button 10 was next depressed, which was. permitted movement by virtue of the tumbler 12 holding thelink outward, and after this. tun1- bler 10 had been brought in alinement it would benecessary to release thebutton 12 tobring its. slot again intoalinement, when by simply depressing the releasing-button D the dog would fall into the slotsor incisions, permitting the, opening. of the lock.

While the hook d is positioned within the opening 25,- the tension of the spring 80 through the link is of course upon the hook d. To facilitate the opening of the lock, the

ICC

lock upon one side is smooth and upon the other milled or roughened, so that the operator the minute he touches the lock will know which side to bring uppermost. If the operator is left-handed, he will prefer to have one side uppermost, while a right-handed operator will prefer the opposite side upward. Then by putting, say, the thumb of his left hand upon the button 8 todepress the same, his second finger upon button -12, his third finger upon button 10, then releasing button 12 and depressing button 13 with the thumb of his right hand, the lock willinstantly fly open. V

To get new combinations, it is of course understood that it is simply necessary to change the position of the slots or incisions within the mutilated tumblers, as well as changethe hook at and projection e in placing the same upon some remaining tumblers. I

The tumblers are mutilated for convenience, so that the rods or bars 0 may readily work between the various tumblers.

This lock can be made of any suitable size or material, and of course a greater or less number of mutilated tumblers could be used. So, also, could another link M be added, if desired.

Now, having thus described my invention, what I claim as new, and desire to secure by United States Letters, Patent, is

1. The combination of a plurality of tu mblers, operating-bars extending from said tumblers, springs to normally force said bars in an outward direction, and a latching-dog pivoted adjoining to said tumblers, said tumblers controlling the movement of said dog in one direction.
